B2 received modules for work in extreme conditions
Unitree has unveiled a modified version of its B2 robot dog that can fight fires. The new model is equipped with special modules, including a powerful water cannon and cooling systems, allowing the robot to operate in dangerous and difficult conditions.
The robotic dog can be used for reconnaissance and video surveillance in fire zones, transmitting images in real time to firefighters. This allows specialists to assess the situation on the spot before the operation. Various equipment can be installed on the body: a manipulator, LiDAR sensors, communication equipment and a water cannon with a range of up to 60 meters and a water flow rate of up to 40 liters per second.
The device can use both water and foam. The gun is adjustable in angle, and the robot itself automatically disconnects the hose if necessary and continues working.
In addition to the main equipment, a water spray system is provided to cool the robot itself during operation in high temperature conditions. Its body is made of composite metal, it is protected from dust and moisture.
There is also a module with a powerful fan capable of breaking the connection between flames and combustible materials when extinguishing forest fires.
The joint performance of the new model is increased by 170% compared to the basic version, which allows it to overcome obstacles up to 40 cm and climb stairs at an angle of 45 degrees. The battery can be changed on the spot without losing its tightness.
The robots have already been tested and have begun working as part of the Qingdao city fire brigade.
